jEl burehelli selousi, hare been proposed for what are at most
local races. But it is at present far from certain whether their
distribution favours this subdivision.
The Quagga was more striped than is sometimes represented in
illustrations. According to Dr. Noack, from whose paper I upon
the animal I quote here, the transverse stripes reached back as far
as the buttocks; they were, however, completely absent from the
legs. The animal is, as every one knows, probably completely
extinct. In the year 1836 it was still abundant; in 1864 the
last specimen, ever exhibited was received by the Zoological
Society. Mr. W. I*. Sclater thinks that it may have survived in
the Orange River Colony as late as 1878, but admits that any
certainty is difficult, as it was frequently confounded by the Boers
with Bluebell's Zebra. Its rarity is emphasised by the fact that
it is not mentioned in the recent work of that most skilful of
hunters, Mr. F. Selous. Qaudry places the Quagga nearest of all
living Equidae to the Hipparion gracile of Pikermi.
Fossil Eqttidae.—The existing Equidae all belong to the
genus JSgwus, though there are some who would (quite unnecessarily)
divide off the Zebras as a genus Hippotigris. The genus Equus
itself goes back in time to the Pliocene, during which epoch there
lived in India IS. sivalensis, the same species according to some
with the J2L stenonis of Europe. None of these species, Old "World
or N&ws are easily to be separated from 38. cabattus. But many
names have been given to them. It is of course perfectly con-
ceivable that they may have differed among themselves as much
as do the existing Zebras and Asses, the separation of which would
be hardly possible did we know their bones only. There are,
however, extinct genera, undoubtedly related so closely to ISquus
as to be placed in the same family, though clearly separable as
genera, Ifipparion is one of these genera ; its remains are known
from Europe, Asia, and North Africa, from beds of Miocene and
Pliocene times. A large number of different species have been
described. It was a beast of about the size of a Zebra. The
principal characters are that each foot has three toes, of which,
however, the two side ones are smaller than the central toe.
